'ro ALL WHQM 1T MAY ooNoEsN;

Beit known that I, JOIN E. SMITH, of Buffalo, in the county ot' Erie, and in the. State of New York, have invented certain new end ilsei'ul Improvements in Meat-0utters; and do lhereby decla-re that the following is 'a full, clear, and Veact'description'of th-e construction and' operation of the saine, referencel being-had tothe vannexeddrawings, making-apart of' thisspeciiication', in Which- Figure l'is a front elevation. A 4 Figure2, a verticalsection'through the frame for holdfing the knives, the inechanism for adjust-ing said frame vertically,` andthe cutting-block'and box, also parl; ofthe franiebelow it.V v

Figure 8 represents a plan .or top viewl of nient-box andrknife-frame. The nat'ure of myinventionY consists in,iirst, placing-the cutting-mechanismen a central shaft, which passes upthrough th'e'eutt'inghloek, said `'shaft receiving its motion from, a crank, or other equivalent mcans,be low the block g. secondi,1maki nlg the knives mijnstahle,l'vertically, on said sha-ft; third, in the employment of 'zt-spring n for preventing, the hreukingoi' the knives bylfragments of' bones onothc'r obstructions, sairl spring being' so arrange@ that the knives willyieldlvirhen an obstruction isA placed beneath them; fourth, in the employment of a double eceentrie,for giving' thenceessaryl movements fo the cutting-block.

A, in said drawings,- represents .the meat-box; B, theeutting-block; C, lthe vert-ical shaft or rod, Vtowhich is attaehecllthc frame holding the knives; D represents said frame; E, the knives, any number of which, from three upwards, may heused. The bolts fonholfling-them on to the frame are marked F. G, in iig.f2, is a ring A or collar, made' to fit andmove easilynp or Vdown the shaft C. It inay be 4fastened firmly, at anypoint on'said shui't C, .y nienns of the set-screw H. Iris the spring, for allowing a yieiding Amotion to the frame null'knives- .when obstructions of any Vkind ('n'hil'e the machine is in operation) come 'in the way. The power 0E tlxesprin-g sregulatleil by thejamnntsJ. As the block is worn away by continued cutting, the cutters and frame rnay be ailjuvstedto ineet it, by means et' 'the'coll'ar .G,set scrcw II, anilljam-nnts` J. K,\in g. 2, represents :i tube, l through which thesha-ft'() works. It passesthrough the centre of the cutting-block, where it is iirinly fastened.

VIt actsnsa support to sni' l`sl1aft C, and also forms a centre', uponwliich the'cntting-blockturns, the lower' port ot' itfworkng inY a socket, L,as shownjn iig. 9. The loir-er end of shai'tC is kept in place bythe brace M', as

, shown in'ig; at N it is mafie. square, as shown, to prevent its turning. "0 is ac'onnecting-rocl,which isjointcd to ithe s'h'ait Q' :it th'e point Q, and to the crank P at the point R, as shown. in saicl fig. 2. 'Ifhe letters S r'eprc- 'sent friction-rollers, which net as supports for the cutting-block, and, at" thesame time, allow it to move easily. '.I and U, in fig. 1,' represent the double eccentric. It islfasterne'cl to the shaft Z. Tir-each eccentric is fastened aJlevcr, as show-n, and niarkeilU and T. .The two levers ereliept in placeor position by a pin, which is firmly ,fastenecllt'o the freine, and passes through 'a slotin eachlever, as shown at V inviig. L W anllX represent two bars ox" springs, vrhiehyare fastenedirmly to the leverSU angl T,.as plainly shown in the drawing. These bars erehent-at the ends, to'i'orm catches, which, during t'liofopern tionV ofthe machine,I are made, by means of the eceweii'tricsftocatch;into' the notehesYgvand gine4 the necessary motions to the meat-box, ivhich must move tiro netehesfor euch revolution of the crank A2, as shown in iig. 1. AThe notches Y are matie of cast iron, in the form of -a ring,f\\'hich7is firmly fastened to the bottoni ori' the cutting-block, as shown. The fraxneworlilof the machine isn'lsofmuileof castiron, and. the knives oucutters of vsheet. steel. 'C2, in iig. 1, 4represents the ily wheel, D2 a spuPlrheel, both 'ofwhich are fastened` to the shaft Z. B2 is a, pinion, which is fastened to the shaft Z2,- and gears ivithjhewlieel'D as shown. l f I Tho machine is operated ,by the crank-whicli, as will be reailily seen, gives .motion'totlie pinion B2, which,

in turn, gives niotion to thewheel Panflconnecting-rod O, which, ofcourse, gives the necessary reciprocating downwar motion of the k'nives'or cutters. r
